To all whom it may concern:

' Beit known that I, AooLPHUs G. MEIER, a citizen of the United States,residing at the city of St. Louis, *State of Missouri, have "inventedcertain new and useful Improve 'rnents in Calculating-Machines, of whichthe following s a specification, reference "being had therein to theaccompanying drawin s.

This invention relates to machines. or mechanically adding individualitems or amounts into an; aggregate or total, and

' especially to adding-machines of that class pawl that act-mates .the

which are adapted .to print the lists of such items or amounts that areregistered, to add up such lists, and to print the total of the addeditems at any desired time.

forming part of this which like numbers of parts wherever they s deelevation .of the In the drawings, specification and in reference denotelike occur, Figure 1 is amachine; Fig. 2 is a longitudinal view on theline;2,2,-Fig. 5; Fig. 3is a perspective detail of a part of one of therack-bars;

after the operating mechanism'isassembled, said casing preventing dustand dirt from settling in the interior of the machine. Cross rods 2extend from one side to the other of the machine, said rods havingscrew-threaded, shouldered heads 3 which heads extend through suitableperforations in the side plates 1. Nuts 4 are screwed upon 3 outside ofthe side-plates 1, thusfirmly seated on the shoulders at the junction ofthe heads and rods, the cross-rods 2 and sidelates -1 being therebybound together to form a skeleton in which the operating partsaremounted.

the heads which are Rods similar in construction and arrange ment torods 2 serve as shafts, or otherwise, to support certain operatingparts, such rods being, for convenience, designated by specificreference numerals. Other cross-rods,

5, are provided for various purposes, these rods being-tapped at theirends for the re ception of screws 6, which are inserted throughperforations in side-plates 1, and

thus these rods, also, can be held'fixedin any Rods 5, unlike rods 2,are

desired position.

heads adapted to extend not provided with through the side-plates 1, butare of thesame length as the internal width of the machine. Thus, rods5, with necessary parts attached thereto, can bepIaced in position inthe machine after the skeleton, consistin of side plates 1 andcross-rods 2, is assemhled, and, since many of the operating parts arepiv otal relation to, or otherwise supportedby,

said rods 5, these parts mayiobviously he) 5 and then the whole groupmounted on rods v k of parts placed in,.or withdrawn frorn,,;themachine, without itslheing necessary to-remove'the side plates 1 or toloosen any-of the'cross-rods 2.

' Rotatably mounted on cross-rod or 7 are the sectors 8, the number ofsectors provided depending on the desired capacity In the drawin s, ninesectors have been shown, which g ves the machine a. capacity for listinany amount from -1 to 999,999,999; but t e same construction may be"employed, and the saine mode of o eration applied, whatever be -thenumber ot sectors and consequent capacity of the machine.

approximately circular 'portion 9, and the radially-projecting arms 10,to which are secured, by means of screws 11, the arcuate keys orfinger-pieces 12, composed of a wide Thesesectors consist ofan I aboutone-fourth of an inch, or less.

,the same distance as it is desired to have between the differentcolumns of figures as they are printed, which distance is usually Toplace all'the finger-pieces 12 within so narrow a compass, however,would prove inconvenient; so the radial arms 10, where necessary, arebent so as to be L-shaped, as. at 16,

and the result is that theparts of the arms I 10 to'which thefinger-pieces 12 are secured,

are spaced apart a considerably greater distanee than are the circularportions 9 from which arms 10 project, and thus, the finger pieces 12may be made of such dimensions, and placed far enough apart so that thekey board, which consists ofthe finger-pieces 12, will be of a sizeconvenient to operate, and will not beunnecessarily crowded.

The finger-pieces 12 are provided for the purpose of registering units,tens, hundreds, thousands, etc., by depressing the respective arms 10and thereby partially rotating the respective sectors 8, theunits-registering finger-piece being the one to the extreme left in Fig.5, the tens-registering fingerpiece being next, to the right, and thenthe hundreds, thousands etd, following in order. Each ofsaidfinger-pieces is provided with a pluralityvof finger-holes orsockets 17 WVhen the operator wishes to register the number that is tobe listed and added, he depresses the appropriate key, or, .if thenumber comprises more than one figure, the appropriate keys, thedistance of such depression of each finger-piece governing, for theparticular column which that key controls, the digit that is to belisted and added by the machine.

The numerals 9, 8, 7, 6, 5, i, 3, 2, 1, and 0 are marked in thefinger-holes 17, beginning towardthe right in Figs. 1, 2, and st, thusindicating the socket in which the operators finger must be placed tosecure the depression of any particular finger-piece the proper distanceto print and add the desired number. Then the finger-piece is depressed,it is moved in the direction of the arrow, Fig. 2, until the finger ofthe operator strikes against the stop 18, when, of course, the fingercan be moved no farther. Accordingly, the extent to which thefingerpiece can move at any one operation is determined by the act ofthe operator in placing his finger in a particular socket of suchfinger-piece, and depressing said finger-piece as far as possible. If,for example, it be desired to register. and add 6 the finger of theoperator will be placed in the'socket designated by the numeral 6, andthe finger-piece 12 thereupon depressed until the finger strikes stop18.

Extending entirely across the machine, and journaled in openings intheside-plates l, is a shaft 19, adapted to be turned by a knob 20 locatedexterior to the casing. Loosely pivoted on said shaft 19 are pawls 21,one pawl being provided for each fingerpiece 12. Springs 22, securedtocross-rod 23, normally keep said pawls 21 -in engagement with thefingerepieces'l2, one such springbeing provided-for each of said pawls,and, as the finger-pieces are depressed by the operator, these pawls areforcedinto'sockets 17, thus to retain the sectors 8, pending theprinting operation, in any position towhich they mayhave been rotated bythe operator. When any finger-piece 12 'i-s;depressed, an( the sector 8to which it is attached thus caused to rotate upon the shaft 7, it is somoved against the resistance of a helical spring '24, one end of aspring 24: being securedto each sector at 25, and all the springs of theseries'being attached at,their opposite ends to cross-rod 26. Thesesprings normally tend to return the sectors 8 to the starting positionshown in Fig. 2, but when any finger-piece 12 has been depressed,and itspawl 21 has been foreed into one of the sockets 17, the finger-piece andits sector are thus locked in place. i f i Bosses 27 are firmly fixed onshaft 19,-and, projecting'from each boss 27, is a pin 28 adapted toengage a pawl 21; When shaft 19' is turned in the direction of thearrow,

Fig. 1, by means of knob 20, the pins 28 coact on the pawls 21 which arethus forced out of the sockets 17 in which they may have seated, and thesprings 24thereupon return the sectors 8 to the starting position. Inthis manner, after any item has been listed or printed, and added intothe machine, the sectors are all simultaneously returned to normalposition, so that the operationmay be repeated and further numbersadded. Pins 31 secured to the pawls limit the return rotation of shaft19, for, obviously, pins 28 can not pass pins 31, but will be caughtthereby. A cross-rod 29, covered with rubber tubing 30, or otherresilient material, against which the arms 10 of the sectors 8 maystrike, forms a cushion-like stop-to limit the returninovement of thesectors and connected parts after the pawls 21 have been withdrawn fromthe sockets 17 in the manner above described.

As hereinabove stated, the finger-pieces 1,2 h avela rubber portion 13,and a metal por 1101114, and the pawls 21 are so loeated that theyengage the metal portion, which will not wear out sd quickly, leavingthe rubber portion untouched by the'- -fingers of the operator.

A plurality=of-arcuate lnet aigstrips 32, supported at one end by across rod 33 and at the other by shaft 19, is provided, and these stripsserve as partitions to keep the various finger-pieces 12 from cominginto contact with oneanother 4 x Projecting radially from the circularportion 9 of each sector 8 are the type 34, by

which the items that are to be added by the machine 'are listed orprinted. These type bear the numerals O, 1, 2, 3, 4, 5, 6,7, 8, and 9,said numerals bein arranged sucoessivel from right to left, Figs. 2 and4.- As each sector8 is given ap'artial rotation upon the depression ofthe finger-piece 12 secured thereto, the ty e 34. borne by said sectorare carried ,upwar in an arcuate path until one of the type-faces is-injuxtaposition to the ribbon '35, The parts are so proportioned that thedepression of a finger-piece 12 to the extent permitted when theoperators finger is inserted in any particular socket 17 thereof willrotate the sector the distance necessary to leave thetype-face 34 whichbears the same numeral as that by which said particular socket 17 isdesignated raised to a point opposite the ribbon 35. Thus, to use theformer example, if the o crater should desire to print 6, he woul inserthis finger in the socket marked 6, depress the finger-piece as far aswould be permitted with his finger in that socket-,whereupon the pawl 21would lock the sector in place by seating in socket '17, and, when thesector had been so locked, the particular type-face 34- that would beexposed to the ribbon springs 24 after the release of the'sec'tors by,

in Fi 515011 35. If desired, the parts can be so.

would be the one on which the character 6 appears. The return of thesectors to norma]. position resulting from the action of the actuationof" shaft 19, obviously, returns all the ty e-faces 34to'the positronshown '2', where no type at all are opposite than constructed that, when81ers returned to normal ,tion, the particular t e-faee 34 bearing thecharacter 0 ,wil exposed to-ribbon 35', this arrangement being preferredby man addin -machine users.

Formed integra with t e circular portion 9 of each sector 8, are teeth36, whichmesh with the teeth 37 offer reciprocating rack-bar 38, therebeing one such bar for each sector.v As the finger -pieoes 12 aredepressed, and the sectors 8 attached thereto rotated, the re;

s -tive bars 3'8 are forced toward-the right,

I igs. 2 and 4,, and, as the sectors are released and returned, the bars38; are" drawn bac sliding wheels '43. Each rackbut thus of eachraek-barf38 causes the appropriate adding wbeel 43 to rotate in thedirection designated by arrow A,'Fig. 11, and pawls 44,'pivoted at 45 tothe partition-plates 46, en age the teeth of each ratchet-whee142 andock said'ratchetand addin wheels against return'movement. Rollers 45spivotall mounted on cross-rod 49 ,Which v passes t rough the opening50in each of the plates 46, are normallyretained in an elevated positionby springs 51.- Said rollers support and keep their respective rack-bars38 in meshwith ratchet wheels 42, but another series of rollers 52 isprovided to prevent undue upward motion of rack-bars 38, which, ifpermitted, wouldcause unneces sa wear and tear on the mechanism;

en the" rack-bars 38 are returned to starting position, the pawls 44having locked the ratchets 42 against return, the teeth 41 of therack-bars ride over the teeth of the ratchets, and, as the rollers 47are adapted to be forced downward against the pressure of springs 51,thereb allowing the teeth of the rackbars to ri e out of the teeth ofthe ratchets, the rack-bars 38 can be withdrawn toward the left, Fig. 2,without disturbin' the adding-wheels 43 or retracting themmm theposition to which they may have beenadvanced.

On each adding-wheel 43 are placed ten type 54. The numerals 0, 1, 2, 3,4, 5, 6, 7, 8, 9, appear upon the type-faces 54 whichradiallyproject'from each of the adding-wheels.

43, and by same the sum of the numbers that have been added is printed.All, parts are so proportioned that the depression of any finger-piece12 rotates the appropriate adding-wheel thirty-six degrees every timethat 1 is to be added by said wheel, twice so far when 2 is to be added,and so on, the amount of rotation depending upon the digit that is to beadded. .At each operation of any key 12 accordingly, the adding wheelcontrolled thereby is rotated, from the position in which'it was last atrest, a distance 7 sufficient to leave exposed to ribbon 55 thetype-facerepresenting the sum of the digit to be added and the one that was lastin that position. Thus, if it should be desired to add 6 thefinger-(piece 12 controlling the proper column Woul be depressed, asheretofore' explained, and the proper rack-bar 38 thereby advanced thedistance necessary to rotate its adding-wheel 43 suiiiciently to leavethe particular type-facebearing, the fi 6 exposed to ribbon 55, assumingthat the addin -wheel had been at 0 when the ration e an. If the t -face2 oftlfg adding-wh eel hadbee'n e ic p osed to the ribbon, it would havebeen advanced to 8 and so on, suitable carrying or transfer v mechanismbeing provided, by means of which each time an addin wheel passes iron:'9 to "0 one unit often or hunupportedin bifurcated yokes 48,

dred, etc.) is carried or transferred to'the wheel next higher in theseries (the one adjacent on the right, Fig. 5) by advancing the latterwheel one number.

The various adding-wheels43 are mounted to revolve idly on a shaft 56,which is supported by the side-plates57. The ratchetwheel 42 connectedwith each addingwheel is located on one side thereof, while, on the sideopposite, is secured a gear-wheel 58. Each adding-wheel is separatedfrom the one adjacent by a partition-plate 46, which plates, as depictedmost clearly in Fi 12, haveperforations 59 through which shaft 56 isadapted to pass, and two arcuate slots GOand 61. Attached to eachpartition-plate 46, or formed integral therewith by bending back atright-angles totheplane thereof the pieces of metal that are stamped outin punching the slots 60 and 61, are cams 62 and 68. The interior ofeach adding-wheel 43 ishollowed out,'and in the cavity 64 so formed isplaced a pawl 65. These pawls are constructed in thevmanner shown inFig.

j 16, having anenlarged middle loop-like part which surrounds the shaft58, from which part pins 66 project into recesses 67 provided-thereforin the hub 68 of each adding-wheel 48.

Each pawl has a stud 69 projecting therefrom, and, also, has extendedportions or heads 7 and 71. These pawls normally remain in a positionwith their studs 69 retracted as far inward as possible i. e., to-

ward the left, 14), but, as each addingwheel is rotated to the pointwhere it is d8? sired to make the transfer, the lowerend 71 of the pawlcarried by saidadding-wheel rides up on the proper cam 63. This forcesthe other end of the pawl outward, and

causes stud 69 to projectthrough slot 60. Each ratchetwheel 42 isprovided with a plurality of sockets 72, separated by the beveled webs73, and as each pawl 65 is thrown into operative position by cam 63,stud 69, projecting through slot 60, sinks into one of the sockets 7 2.As each addingwheel revolves, stud (S9 of the pawl carried therebystrikes one of the webs 73 of the adjacent wheel, and thus each wheelrotates in unison with the wheel next higher in the 'series during suchlength of time as its pawl is-thns permitted to protrude through theadjacent slot 60. In order to withdraw the pawls, cams 62 are provided,and, as the Wheels 43 rotate, the heads of the pawls ride up on saidcams, and the pawl carried by each adding-wheel is thereby lifted out ofengagement with'the adjacent adding-- wheel. The size of the parts, andtheir arrangement is such that each pawl is per-. mitted to projectthrough its slot 60 during the time that the adding-wheel'by which it iscarriedis passing from 9 to 0, and

no longer. 1 During such time, therefore the vanced, but, as the shaftpawls 80 is rotated, said pawls Wlll drop cated transfer is made, and ateach revolution of any one adding-wheel 43, one unit, (or ten, orhundred, etc). and only one, is transferred or carried to the wheel nexthigher in the series, the latter wheel being advanced one number.

It will be observed, by reference to Figs. 2 and 4', that when anyrack-bar 38 is in normal or starting position, the beveled teeth 41thereon do not reach as far as the ratchetwheel 42. The purpose of thisconstruction is to permit the finger-pieces to be depressed to v 0without communicating motion to the adding-wheels. Unless thefinger-pieces are depressed to 1 or beyond, the addingwheels do notrotate at all. i I

J ournaled in bearings 74 in the side-plates 57, and projecting beyondthrough the side, is a shaft 75, adapted to be rotated by a knob 76attached thereto but located exterior, to the casing. Idlyrevolving onthis shaft are gear-wheels 77, which, while the adding operation is inprogress, mesh with, and are driven by, gear-wheels 5,8. In the hub 78of each of said wheels 77 is a notch 79. Secured to said shaft 75 arebosses 80, each boss pivotally supporting a spring-pressed awl 81, saidpawls being in alinement witheach other. When the adding operation'is inprogress, and the adding-wheels 43 are rotated, the gears 58 cause thegears 77 to revolve idly in the direction indicated by arrow B, Fig. 11,but when it is desired to clear the machine, or return all theadding-wheels to O, shaft 75 is rotated in the directionindicated bysaid arrow. As

the shaft 75 is thus rotated, the pawls 81- one by one drop into thenotches 79. This locks the heretofore idle gears '77 to the shaft 75,and causes them to rotate therewith, and, as these gears 77 mesh withthe gears 58, the latter are, also, rotated, carrying with them theadding-wheels 43. After the addin notches 7 will be variously positionedaround the shaft 75, the position of each notch depending on thedistance that the particular adding-Wheel which rotates its gear 77bearing said notch has been ad- 75 bearing the into the proper notches79- wherever they may be, and each adding-wheel Wlll be f picked up andits rotation commenced as soon as the proper pawl drops into the notch79 on the gear 77 opposite said adding operation has been completed,

adapted to aline with anothermark on the side-plate 1. l Mounted on astud-like shaft 82, which projects from the'side-plate. 1,.is theoperatlug-lever 83, which is moved when it is desired to print thevarious numbers that are registered, or .the sum thereof. Springs 84 and85 have one'end secured to a button 86 formed on the lower end of thislever, and their opposite ends are fastened by rivets 87 to -the sideplate -1. When this lever is' movedgn elther direction the contractionof the particular spring that has been expanded tends to return saidlever to the normal position shown in Fig. 1; Brackets 88, pro- 1ecti-ngfrom side-plates 1, have screwthreaded. openlngs in which are placedthumb-screws 89. These s'crews lie 1n the are through which theoperating lever 83 travels, and limit the movement thereof,-

and, obviously, by turning these screws one way or the other, the limitto which the op-.

crating-lever; may be moved, can be regulated to whatever extent may bemade necessary in the adjustment of the parts of each individualmachine. Nuts 90 ma tightened to hold the screws in ti'on.

Encircling the stud-like shaft82, and se-'' cured to lever 83 by meansof screws 91, is a gear-wheel 92, which rotates as the lever is moved.Thlsgear meshes with and drives gear-wheel 93, which is secured to astud like shaft-:94, ournaled in a suitableperforation providedthereforin side-plate 1. Formed integral with shaft 94 is a rocker-arm95,. and on. the opposite side of .the machine is asimilar rocker-arm96, pivotal'ly mounted, by

means ofstud 97 in the opposite side-plate 1. Depending from eachrocker-arm is a flat stud 98, which studs are inserted in slots 99formed in t'he ends of rod 100, said rod thus serving to cross-connectthe two rockerarms 95 and 96, thereby causing them to move in unison.Consequently, when ..the rotation of gear 93 .causes shaft 94 torevolve,

the rocker-arms 95 and 96 rotate in unison about studs 94 and 97 as anaxis, thedirec-,

. tion of such :rotation being. determined by roller isgiven a partialrevolution at eachoperationof the lever 83, and the paper ribbon104,'onwhich the items are to be prmted,

.is thus advanced to leave suflicient spacethen be xed' posibetween thedifi'erent lines. Two shafts 106 and 107 are, also, journaled in therockerarms, said shafts supporting friction rollers 108 and 109 whichbear against the platenroller 103 and keep the paper ribbon 104stretched taut. ported on a core 111 which rests in sockets or slots 112provided therefor in the sideplates 1, and, as the ribbon 104-leaves thereel,.it passes between friction-roller 108 and the platen-roller,thence around the platen, being held thereagainst by the other frictionroller 109, and emerges through the s cebetween'. the two rollers 108and 109, rom whence it can be removed at the operators conveniencewhenever'the desired addition and im rint have been completed.

A bi urcated pawl 113, the two arms 114. and 115 of which are spacedapart a sufficient distance to per-mit'the rocker-arm 95 'to passtherebetween, is provided at one end with a sleeve 116, by means ofwhich and a screw 11'? passing therethrough and fitting into a tap-hole(not shown) provided therefor, said spring is mounted upon the side- Thepaper reel 110 is supplate 1. .Ifdesirable, however, the pawl 113 may bemounted in any other convenient manner. The wl'is so arranged thatitsshort arm 114 has the ath of travel of the ratchet-wheel. 105, an, asthe rocker-- arms and 96 are swung toward the left,

Fig. 2, am 115, which is, in reality, a spring pawl, engages the teethof ratchet 105 and causes said ratchet to rotate, together with theplaten roller 103, both of which members are fixed to the same shaft102. This operation secures 1 the step-by-step forward feed of the paperribbon which it is. necessary to provide, in order to have each numberprinted'on a separate line. In the other .arm, 114, is a recess 11.8,and a pin 119, project-ing-from rocker-arm 95, is seated therein whenthe parts are in the normal position depicted in Figs. 2 and 4. \Vhenthe platen is moved out'of this position, the pin 119, riding outof saidrecess, slightly elevates arm 114, and, in consequence, arm or pawl-115is, also, raised, and lifted out of engagement with ratchet 105, theparts being so proportioned that pawl 115 is thus'llfted when'theratchet has been advanced the distance of one notch. The spring-arm 114,by hearing down on pin 119, tends to keep the platen locked in normalposition after the springs 84 and 85 have returned the various partsthereto, and thereby prevents an unpleasant vibration that might occurif no means but the springs 84 and 85 were pro vided for holding theparts at rest. It will thus be seen that, as the operator, grasping thehandle 120, moves the lever 83 toward the right, Fig. 1, gear-wheelrotates ear 93, thereby causing the revolution of s aft 94, and,consequently, the rocking of arms 95 and .96, and the rollers carriedthereby.

The arms continue thus to move until the,

, platen 103 strikes the type 34, the ribbon feeding between said typeand said platen, which type, by operation of the fingerpieces 12, havebeen raised into place. As

the platen strikes these type, the numbers they bear are printed on thepaper-ribbon .1104, after which the lever 83 is released, and

' the spring 84 returns the lever and platen to i'normal position. Whenthe operator desires :t-o'obtain and-print the sum of the various lever.83 strikes thereupon simultaneously.

with thestriking of platen 103 on the type, thus permitting thema'jorpart of the percussion to be borne by the lever and screws rather thanby the platen and type, thereby helping to reduce the wear and tear onthe more delicate parts of the mechanism.

The ribbons 35 and 55 are carried on reels 121, which are rotatablymounted in suitable brackets 122 projecting from and exterior to theside-plates 1. The ribbons may be fed forward by manual operation of theknurled knobs 123, which are secured to each reel, or by suitableautomatic ribbonfeed mechanism, which, forming no part of the presentinvention, is not herein described in detail. The ribbons pass into theinterior of the machine through slots 124 provided therefor in theside-plates 1.

It will be seen that the accumulating.

, mechanism is all carried between the sideplates 57, and is entirelyindependent of the printing mechanism. Brackets 125 are fastened tothese side-plates, and secured thereto are rods 5, the construct-ion ofwhiclr-is herein above described. If it should, at

* any time, become necessary to make repairs on the accumulatingmechanism, it may be removed in 150250 without disturbing the residue ofthe machine. The only members in termediate the accumulating mechanismand the sectors 8 are the -raclrbars 38, .and these are constructed withtheir right-hand ends, Fig. 3, of such size that they may be inserted inplace underneath the addingwheels, or removed therefrom, with littledifficulty. These rack-bars are grooved at 126, and the rollers 39 and47 ride in these grooves, thereby preventing any side-swaying of therack-bars as they travel.

In the adjustment of parts, it will, of course, be necessary to have theaddingwheels 43 alining'with the type 34, so that the figures to beprinted by the addingwheels will be in the same columns as'those ofthe'corresponding denominations printed by the type 34. Ratchet 42 andthe teeth 36 on the sector 8 are, therefore," not in aline= ment, andthe teeth 41 on the rack-bars 38 are set to one side, as shown in Fig.3, rather than along the center of the bar. These teeth, accordingly,will not strike the type 34 on the sectors 8 when the parts are returnedto starting position, but-will be to one side, as in Fig. 2. Therack-bars have a cut-away part 127 which gives the adding- Wheels 43sufficient space in which to revolve. The side-plates 57, which supportthe accumulating mechanism, are bound together by the shafts 49 and56,by rods 128 and 129, which rods, also, support the springs 51 and byotherrods 130, and thus the accumulating mechanism is grouped by itself,in a frame comprised of the side plates 57 and various cross-connectingrods.

i In many addingmachines, there is an undesirable profusion of partscross-connecting the different sections, makingsuch machines expensive,complex in construction, and difficult to assemble, but in the presentinvention the listing mechanism, accumulating mechanism, and mechanismsupporting andactuating the platen are all grouped independently of eachother, save for the rack-bars 38which connect the list-ingto theaccumulating mechanism. Thus, each section of. the machine can beseparately as-' sembled and placed in position, and, after that is done,and the simple. operation of adjusting the rack-bar is performed,themachine will be ready for use. The rackbars give a positive'm'otionto the addingwheels, while in nearly all other machines the addingmechanism is spring-actuated, which, o:t' course, makes successful andaccurate operation more difficult to secure.

The operation of'the machine, in so far'as it has not already beendescribed, is as follows: the particular digit of each denomination tobe added is determined by the extent to which the proper finger-piece 12is depressed, and the extent of such depression depends, in turn, uponthe particular socket 17 of said finger-piece in which the finger of theoperator is placed. As fast as each finger-piece 12 is depressed to thelimit permitted with the finger placed in any particularsocket, and thesector 8 to which it is secured thereby rotated, one of-the pawls 21locks the sector and attached parts against return movement. By therotation of the sector, the type 34 carried thereon are raised until theproper type-face is at a point opposite the ribbon 35, and,simultaneously there- 'with, the rack-bar 38 engaging said sectorisdriven forward, saidbar in turn causing the proper adding-w11eel- 43to rotate the distance necessary to make.the type 54 which is-then leftexposed to the ribbon 55 represent the sum of the number at'which theadding-wheel last stood and the new digit that has been added in. Whenall the necessary finger-pieces have been depressed, it is obvious thatthe proper type 34 which will then be in a position opposite the ribbon35, will representthe desired number, which number may then be printed.To print the numbers, the operator moves lever 83 to the right, Fig. 1,thus causing the platen 103 to move and strike the type 34, whichthereupon print their respective figures on the paper carried by theplaten. The number having been printed, the lever is released, spring84: acts thereupon'and returns. it, together with the platen, to normalposition, where the platen mechanism is locked against vibration by .thebearing of spring 114 upon pin 119. Knob QO'is then turned in thedirection of the arrow, Fig. 1, the pawls' 21 are thereby withdrawn fromengagement with the finger-pieces 12, and springs 24 cause the sectors 8and connected parts to fly back to the starting position. The returnmovement of the rack-bars 38 will not, however, affect the adding-wheels43, as pawls 44: lock these against return movement. These operationsmay berepeated ad Zbz'tum, so long as there i are any numbers to beprinted and addedf IIIOHOII 111 n Sa rollers belng and at each operationof the operating-lever 83 the platen is given a partial revolution.by'the action of pawl 115 on ratchet I05, toi aper ribbon forward. Finally,;

feed :the when all t e numbers'lto be addedhave been thus registered andprinted, theoperatingf lever is pulled toward the left, Fig. 1, therebybringing the platen 103 into engagement z with the type '54 of theaddingwheel's 4G3; which print the sum or total of the column of itemsupon the paper ribbon 104. Knob 76 may, thereupon, be turned, and themachine cleared.

In cases where it may be desired merely.

to ascertain the sum of certain numbers, without printin or listingthem, the various numbers may e registered in the usual manner, but theoperat-ionsof the lever 83 omitted, except, possibly,the final one,which causes the sum itself to be printed. Sub;

totals may be obtained at any desired intermediate point, and the addingoperation thereupon resumed, because the machine is not cleared by .;themere printing of a total," since the clearing requires the "inde-'pendent and distinct operation hereinbefore described.
